So I spent an hour and a half in Wrothgar killing everything in sight. I was merciless and brutal, slaying mudcrabs like a total boss.
18 Rubedo Leather scraps. 160 Shadowhide scraps. Now, that's not how it has always been, and I don't think this patch sneakily nerfed drop rates for Rubedo leather, so sometimes I do get more Rubedo than just 18. RNG gods were not with me today.
I wish the drop rate for Rubedo scraps were higher to make up for the lack of nodes, especially when it comes to surveys. For cloth, metal and wood, the surveys give you more than enough material for the next writ. That's why I am doing them at this level even though it requires over 9000 mats for a set of armor. But it's mainly because I only need Rubedite for metal weapons, Ruby Ash for bows and staves, and I already crafted my Vet 16 weapons.
Another idea, as I hinted in my title, is to have a leather node spawn for surveys. I'd think one way this could be is in the form of a 1 hp animal, probably a deer, that has a special name and a unique looking hide. It only appears for the player and instead of killing it by attacking, there is a kill and harvest animation like with a plant and the deer disappears. A crowd of deer might not make sense. If there were just one of these exceptionally endowed (I'm talking about hide here) deer, perhaps they drop around 25-30 scraps, and on Wrothgar this is guaranteed to be Rubedo leather.
Maybe the deer could have different color hides for whatever material they drop - such as red for Rubedo leather or black and blue for Shadowhide and so on... and they sparkle if there is that Keen Eye passive active.
